NXP I2C/SPI master bridges SC18IS600/601, SC18IS602/603, and SC18IM700 Connect I2C/SPI slave or UART to I2C/SPI master or GPIO These compact protocol converters create seamless, low-power, low-voltage interface connections, so they make it quick and easy to add I2C/SPI master and GPIO capability to any application that has an I2C/SPI bus or UART host interface. The result is increased design flexibility with reduced complexity and software overhead, and faster time-to-market.

The I2C-bus controller has multi-master capability, so it can share the bus with a microcontroller or another I2C master. The high-speed SPI bus slave operates at up to 3 Mbps. SPI These low-power bridge ICs simplify design and reduce system cost by making it easy to add devices to an application. They provide an I2C/SPI master interface control to the I2C/SPI bus without a remote host processor. They also provide access to GPIO, so it’s easy to expand the host system to support additional functions: 4 System monitoring 4 Diagnostics 4 LCD display control 4 Fan control 4 LED lighting/blinking 4 Button/keypad press detection 4 Status information 4 EEPROM data storage Fan control Reset signal Push button SC18IS600/601 usage scenario SC18IS602/603 The NXP I2C/SPI master bridges SC18IS602 and SC18IS603 let a host with an I2C bus communicate transparently with SPI-bus devices like LED/LCD displays, temperature/voltage sensors, and EEPROM data storage. The SPI-bus controller can select up to four SPI slave devices. The high-speed SPI bus slave operates at up to 4 Mbps. SC18IM700 The NXP I2C/SPI master bridge SC18IM700 lets a host with an RS-232 connection communicate with remote I2C devices such as temperature sensors, LCD displays, A/D converters, and smart card readers. The same RS-232 connection can also be used to let the host communicate with remote GPIO. Both devices support 2.4- to 3.6-V operation and offer up to four GPIO pins when they are used to select SPI slave devices. The I/O pins are tolerant to 5 V. The device supports 2.3- to 3.6-V operation and offers up to eight GPIO. The UART host interface delivers baud rates up to 460.8 kbps, and the fast I2C-bus, which supports multi-master capability, operates up to 400 kbps. Both have 200-byte on-chip data buffers, support low power mode, and provide active-low interrupt output. They operate in the industrial temperature range and are available in a 16pin TSSOP package. It integrates 16-byte transmit and receive FIFOs, supports the 8N1 RS-232 format, and uses a wake-up pin to support powerdown mode. It operates in the industrial temperature range and is available in a 16-pin TSSOP package.
